Functional Medicine
A retail pharmacy that will not compound the protocol you actually run — that’s why Ann Arbor clinics call. We compound functional medicine compounds patient-by-patient and ship from Florida.

Promise Pharmacy is a 503A compounding pharmacy in Palm Harbor, Florida. It prepares patient-specific functional medicine compounds and ships them to licensed providers in Ann Arbor, MI — Ann Arbor is a mid-size city of about 119,381 residents in Washtenaw County (U.S. Census Bureau, Vintage 2023 population estimates). Typical transit after dispatch is 2–4 business days. There is no Ann Arbor storefront.
Service area — shipping, not a storefront
Providers in Ann Arbor can discuss patient-specific strengths, dosage forms, and availability for functional medicine compounds with our compounding team.
Ann Arbor (119,381 in Washtenaw County, U.S. Census Bureau, Vintage 2023 population estimates) loses winter days to weather. An unattended porch is a worse destination than a staffed suite when the compound is temperature-sensitive. Typical transit is 2–4 business days.
We do not operate a compounding bench in Ann Arbor. Promise Pharmacy is a 503A pharmacy at 31818 US Hwy 19 N, Palm Harbor, FL 34684. Patient-specific compounds for Ann Arbor are prepared there, then shipped to the clinic or the patient named on the prescription. Local walk-in service and pickup are not available in Ann Arbor.
Every tested batch has a Certificate of Analysis in the provider portal. If a Ann Arbor medical director wants the COA on file before the first patient injection, that is a normal request, not a special favor.
Ann Arbor is in Washtenaw County. We ship patient-specific compounds to clinics and patients in Ann Arbor.
Winter in Michigan delays trucks and freezes doorsteps. Refrigerated preparations for functional medicine compounds ship in insulated packaging with season-appropriate cold packs. If a Ann Arbor clinic would rather take delivery at the suite than leave a carton on a stoop over a weekend, we ship to the suite. Typical transit after dispatch is 2–4 business days.
Amy Patel, RPh, our COO, has more than 25 years in sterile compounding. Clinical questions from Ann Arbor accounts go to our compounding team in Palm Harbor.
Michigan has broad telehealth prescribing parity compared with many states, which is why video-first functional, integrative, and longevity clinics in Ann Arbor are a normal account type for us. Controlled substances are still federal: testosterone remains Schedule III, and state telehealth laws do not waive Ryan Haight requirements. For the underlying 503A vs 503B split, we keep a longer explainer on 503A vs 503B compounding.
Michigan permits licensed nonresident pharmacies to ship compounded prescriptions and has a large healthcare provider workforce. Verify a pharmacy license on the Michigan Board of Pharmacy site for current licensure information.
